电气自动化是工业、农业、国防、科技现代化的关键性技术和根本保障,是一个国家现代化程度的标志。电气自动化从最初的只能对重复执行的机械过程进行自动化,发展到现在可以对模糊的过程甚至对随机的情况进判断处理,其间经历了漫长的过程。这其中涌现出了三种控制系统:PLC、DCS、FCS。这三大控制系统分别引领了各自的一个时代,也正在进行着更新替代。现就以这三大系统为例对电气自动化控制系统的发展过程与展望做一个深入的阐述。
Electrical automation is the key technology and fundamental guarantee for the modernization of industry, agriculture, national defense and science and technology and is a symbol of the degree of modernization of a country. Electrical automation has gone through a lengthy process, from initially automating only repeated mechanical processes to being able to process fuzzy processes and even random situations. There are three kinds of control systems emerged: PLC, DCS, FCS. The three control systems have led their own era, are also undergoing an update replacement. Now on the three systems as an example of the development process and prospects of electrical automation control system to do an in-depth elaboration.
